"By the power of Grayskull... I have the Power!" And he still has after all these years! ;) The He-man action figure was released in 1982 by Mattel and was part of the Masters of the Universe toy line, movie and tv series. He-Man is "the most powerful man in the universe" and in most media he is the alter-ego of Prince Adam. He is armed with a power harness that enhances his strength, the Sword of Power, a battle axe, and a shield.
